Riot, so copying LB ult only lets Sylas use HER last used spell?

At least thats what I get from this video https://youtu.be/VcfLR39GaUk?t=5m20s . Thats kind of a shame, I was sure it would let him recast one of his spells (maybe with increased base numbers and scalings; not sure if that would be too opie). Also I really feel like Twitch ult should do more. Its nice to get range, but the bonus AD Twitch ult gives alone doesnt really make it useful since Sylas doesnt build AD nor attack speed. Maybe the auto attacks could scale off AP and his attack speed while using Twitch ult could be based off his CDR?

Other ult interactions like Karma/Heimerdinger and especially Jayce/Nidalee/Elise/Shyvana are amazing tho, good job with this champ!
